Orange Pi Zero 4 4GB: Strengths & Caveats
✔ Advantages
- Dense heterogeneous octa-core CPU paired with an integrated 3 TOPS NPU and real-time RISC-V coprocessor
- Dual independent 4K 60Hz display pipelines via Mini HDMI 2.0 and USB Type-C DisplayPort Alt Mode
- Modern networking suite with Wi-Fi 6, Bluetooth 5.4, and Gigabit Ethernet in a 50 x 55 mm footprint
- Versatile expansion capabilities including single-lane PCIe 3.0 FPC and dual 4-lane MIPI CSI camera interfaces
✖ Documented Caveats
- PCIe 3.0 bus expansion relies on a 16-pin flexible flat cable (FPC) socket rather than a standard M.2 slot
- Display output requires a Mini HDMI adapter or specialized cable for conventional monitors
- High-speed onboard eMMC or UFS 3.0 storage requires specific hardware footprint configurations
Raspberry Pi 5 2GB: Strengths & Caveats
✔ Advantages
- 2x to 3x CPU performance uplift over the previous generation via modern Arm Cortex-A76 cores
- Refined silicon revision with improved power efficiency and reduced thermal dissipation
- Dual 4Kp60 display capability powered by the upgraded VideoCore VII graphics engine
- Industry-leading long-term firmware and mainline Linux operating system support
✖ Documented Caveats
- 2GB memory ceiling limits intensive multitasking and heavy containerized workloads
- Requires auxiliary active or passive cooling accessories to avoid thermal throttling under peak compute loads
